Can someone check my answer for:
Simplify 11√8 +√12 - 5√2
I checked my answer on Wolfram and it says the answer is 17√2 + 12√3

But this is how I got my answer:
11√8 = √2 * 4 = √2 * √4 = 2√4 = 2√2
6√12 = √3 * 4 = √3 * √4 = 3√2
- 5√2 cannot be simplified anymore

2 + 3 - 5 = 0
√2 + √2 + √2 = √2

Combine everything:
√2

Have I done something wrong, or do I have the right answer?

$$11 \sqrt 8 + \sqrt 12-5 \sqrt2= 11*2 \sqrt2+ 2 \sqrt3-5 \sqrt2= 22 \sqrt2-5 \sqrt2+2 \sqrt3$$

ghazi · Answer

$$17 \sqrt2 +2 \sqrt3$$ should be the answer

anonymous · Answer

how come the 6 was taken out of 6√12?

ghazi · Answer

$$\sqrt{12}= \sqrt {2*2*3}= 2 \sqrt 3$$

anonymous · Answer

Oh, I just relooked my question! Sorry. I forgot the 6.
